ABSTRACT:
A scooter includes a body having four pulleys at four corners of the body. A wire reeves through the pulleys. A head tube is connected to the body, and a handlebar stem with a front wheel rotatably extends through the head tube. A rear wheel is connected to the rear part. Two pedals are fixedly connected to the wire, and toothed belts extend through the pedals. Each pedal has two wheel sets. Each wheel set has a shaft on which a one-way bearing is mounted. A gear is connected on the the one-way bearing and is engaged with the toothed belts. Wheels of the wheel sets contact the ground, and the scooter moves by reciprocally shifting the pedals on the toothed belts.
